Aperture, Shutter speed, & ISO

They iris and pupil relate to aperture the most because they control how much light passes into the eye just like the aperture controls how much gets into the camera.

The smaller the aperture the less light that passes through, the bigger the aperture the more light that passes through. 

When there is a larger aperture their is a large depth of field, but when its smaller it makes a small and shallow depth of field.

Fast

Slow

 When the sun was still up it would be better to use a medium shutter speed for booths under shade, and fast ones for booths like the dancers and basketball.

When the sun has gone down it would be better to use a slower shutter speed to capture more light except on the fast moving stuff like basketball, you would need a medium shutter speed. Unless you want to create motion blur.

When the camera is in auto mode the camera picks the shutter speed. When it is in shutter speed priority you pick the shutter speed and it sets the aperture. There is also manual where you set both the shutter speed and aperture.

The effects of a higher ISO at a dark football game or a basketball game are that it brightens the picture. It will brighten the back ground and also the subject.

The author suggests that we use a lower ISO in well lit conditions. 

Lower lit conditions require a higher ISO. If it is too high then it might create noise or even motion blur.

The aperture settings are 2.8, 4, 5.6, 8, 11, 16, and 22.

The shutter speed settings are 1 second, 1/60, and 1/4000 of a second.

 The ISO settings listed are 100, 200, 400, 800, 1600, 3200, 6400, 12800,  and 256000.
